摘要: 高阻尼橡膠支座因其獨(dú)有的阻尼特性和環(huán)保優(yōu)勢受到日益廣泛的關(guān)注和研究,國外研究機(jī)構(gòu)關(guān)于高阻尼橡膠支座已有較為完善的研究成果。 為推動高阻尼橡膠支座在我國的研究和應(yīng)用,亟需系統(tǒng)梳理和思考現(xiàn)有研究成果。 首先梳理了國內(nèi)外高阻尼橡膠支座基本力學(xué)性能的研究脈絡(luò)和情況,而后重點(diǎn)對高阻尼橡膠支座力學(xué)模型的相關(guān)研究進(jìn)行了總結(jié),討論了現(xiàn)有速度無關(guān)性模型和速度相關(guān)型模型的優(yōu)勢與不足;總結(jié)了豎向壓力相關(guān)性、剪切應(yīng)變相關(guān)性和溫度相關(guān)性對高阻尼橡膠支座力學(xué)性能的影響。 最后簡述了高阻尼橡膠支座穩(wěn)定性的研究現(xiàn)狀。給出了高阻尼橡膠支座在復(fù)雜受力性能、極限荷載作用穩(wěn)定、反復(fù)荷載作用疲勞等方向的相關(guān)研究建議。

Abstract: High damping rubber bearing (HDRB) has received more and more attention and research owing to its unique

damping characteristics and environmental protection advantages. Foreign research institutions have relatively complete

research results on HDRB. In order to promote the research and application of HDRB in China, it is urgent to systematically

review and consider the existing research results. Firstly, the research context and situation of the basic mechanical

properties of HDRB at home and abroad were reviewed. Then, the relevant research on the mechanical model of HDRB was

summarized, and the advantages and disadvantages of the model with rate?dependent and the model without rate?dependent

were discussed. The influence of the factors on mechanical properties of HDRB was summarized, including vertical pressure

dependence, shear strain dependence and temperature dependence. Finally, the research status of HDRB stability was

briefly described. The relevant research suggestions for HDRB in the directions of complex mechanical performance,

ultimate load stability, and repeated load fatigue were given.

Keywords:seismic isolation; high damping rubber bearing; mechanical property; rate?dependent; stability
